Today’s LiveWire Spotlight evaluates six slide-decks shown at last January’s Inverter-Based Resource Performance Task Force (IRPTF) meeting addressing the latest advances in inverter modeling and operational performance during contingencies. The presentations offer findings of interest to all Registered Entities responsible for transmission integrity, power system balance, and frequency/voltage response – whose ability to assure reliable performance is being stressed as the penetration of renewables increases.

The rapid integration of inverter-based resources has introduced a series of new challenges for electric system owners and operators.  If allowed to persist, these issues will be harder to resolve as the grid’s dependence on renewables grows.
